Dual-listed Gemfields, which remains intent on listing on the Aim, delivered a “profitable, but varied” performance during the first half of the year, ended June 30, chairperson Brian Gilbertson said on Friday. He explained that, when compared with the first half of 2018, total rock handling had increased by about 20%, but the recovery of emeralds and rubies in the premium category had decreased by about 37% as the gemstone producer navigated areas yielding lower premium-carat grades.
